b. Tourist boats
Since pre-cooking of food materials on land is effective to reduce waste and wastewater generation on boats, this method was introduced and promoted to managers of tourist boat companies as a good and simple approach for the environmental protection at seminars and workshops, which were organized to raise aware on the importance environment protection of Ha Long Bay. Through this process, some other tourist boat companies started purchasing pre-cooked food materials from retailers, which make the same effect in the reduction of waste and wastewater reduction on boats. Therefore, the second method was also promoted for the tourist boat companies, too. With these efforts, the two approaches have come to be adopted by many tourist boat companies by the end of the project.
